On Reddit, a user asked:
I am wanting to switch podcast hosting services. When I switch, will all the podcast directories upload new episodes when I put the link to my new RSS feed into the RSS feed redirect of the old host? For instance, after I switch services and upload a new episode via the new hosting service, will Spotify, iHeartRadio, Google Podcasts, Stitcher etc have the new episode listed?
Here's what we recommend!
Marco Arment, the creator of Overcast, notes the importance of Apple Podcasts:
The iTunes Store's Podcasts directory is the only one that matters, and being listed there is essential for podcasts to be easily found when searching in most apps.
So, your first step is to log into your account on Apple's Podcast Connect, find your show, and paste in your new feed URL.
While most apps and directories (like Overcast, Pocket Casts, Castro, Breaker) will scrape Apple's podcast directory, there are a few other "walled gardens" that you'll need to update manually.
Now it's time to go back to your former podcast host (Simplecast, Libsyn) and forward your old feed to your new podcast feed:
(To see what this looks like on our platform, read this guide).
After you've redirected your old RSS feed to your new feed, it's best to wait two weeks before you delete your old hosting account. Also, it can take 24-48 hours for Apple to propagate your new feed on their platform. Be patient!
